arm: Fix vfp_operand_register for VFP HI regs

[Christophe Lyon via Gcc-patches]

Hi,

While looking at PR target/94743 I noticed an ICE when I tried to save
all the FP registers: this was because all HI registers wouldn't match
vfp_register_operand.

Regression-tested and bootstrapped OK.

        gcc/
        * config/arm/predicates.md (vfp_register_operand): Use VFP_HI_REGS
        instead of VFP_REGS.

OK?

Thanks,

Christophe
